Kinesis support

[renecouto]

Hi I'm looking to contribute to this project while learning Haskell. Can I work on adding Kinesis actions?

I have some more questions:

• Should I implement every action possible in a single PR can I start with the most useful ones? (ex: create/read/delete stream, list/read shard)
• I think there will be a lot in common between this and DynamoDB (Region, endpoint configuration, signing). Should I try to generalize these configurations in a previous PR, or do I just copy and paste code, and after it's merged and it looks useful I'd add another refactoring PR?
